Specification of Letters Patent.

Patented May 11, 1915.

Application filed June 11, 1914. Serial No. 844,493.

To all whom it may concern:

Be it known that I, GEORGE F. SHERMER, a citizen of the United States of America, residing at Columbus, in the county of Franklin and State of Ohio, has invented certain new and useful Improvements in Swings, of which the following is a specification.

The present invention relates to improvements in swings, and applies particularly to a novel form of rotatable seats carried by the swing.

The primary object of the invention is the provision of a swing possessing seats capable of being rotated to adjust them to different positions with relation to each other and to the fixed frame of the swing, whereby the seats of the swing may be used for a variety of different purposes aswill be hereinafter explained.

The invention consists in certain novel combinations and arrangements of parts whereby the seats carried on the swing frame may be rotated to desired positions, and held locked in such positions by means simple but effective and facile in manipulation.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of my invention.

Figure 1 is a front elevation of a swing illustrating thereon two rotary seats, the support for the swing being omitted. Fig. 2 is a plan view of Fig. 1 with one of the swing seats omitted for convenience of illustration. Fig. 3 is a transverse vertical sectional view of Fig. 1. Fig. 1 is an enlarged, transverse sectional view showing the rotary connection of the seat to the swing frame. Fig. 5 is a plan View of a seat plate detached. Fig. 6 is a view showing a portion of the swing frame in section with a table attached thereto. Figs. 7, 8, 9, 10, 11, are diagrammatic plan views showing the different results capable of attainment with the rotary seats.

In the preferred embodiment of my invention I employ a rectangular frame made up of the two side bars 1 and 2 which are connected at their ends by the pair of end bars 3. The ends bars 3 are preferably of metal and fashioned or shaped with upturned ends 4:, 1, perforated at their extremities to ac commodate the chains 5 by means of which the swing frame is suspended from a suitable support in such manner as to be free to swing as usual. The longitudinal side bars 1 and Q'may be of suitable wood and they are spaced apart'and bolted to the end bars at points equidistant from the center of the end bars, as clearly seen in Fig. 3.

I have illustrated two seats 6 and 7 in the drawings, but it will be understood that the number may be increased or diminished as desired. In any event the construction of allseats is identical, and I shall therefore use the same reference characters to indicate duplicate parts in the two seats 6 and 7 Each seat is supported from the rectangular frame, or more particularly from the longitudinal side bars 1 and 2 of the frame, by means of a pair of leaf springs or spring plates 8, 8, which have their body portions projecting above the plane of the two side bars and their ends passed under the bars and curled over the top and fastened thereto by bolts 9, 9. These leaf springs are spaced a suitable distance apart on the side bars and are connected by the circular disk or base plate 10, formed with diametrically arranged lugs 11 that .are bolted as at 12 to the leaf springs or spring plates. This disk or circular plate is provided with an interrupted overhanging flange 13 which forms an annular groove about the perimeter of the disk or plate. At its center the base plate is formedwith a depression or recess 14 in its upper surface, while below or on the under side of the plate a pair of perforated ears or lugs 15 are cast in which to fulcrum the pivoted latch lever whose long weighted arm 16 extends out beyond the edge of the disk and forms a handle, while its upwardly bent short arm 17 forms a latch and is passed through a perforation 18 and projects above the upper surface or face of the plate.

A. bottom plate 19, which is carried by the seat, is adapted to co-act with the base plate 10. The bottom plate is also circular in outline and has four perforated arms 20 by means of which it is attached to the underside of the seat of the swing, the arms being bent or extended upwardly above the plane of the plate so that the body portion of the plate may project beyond the plane of the attaching arms. In addition to the four attaching arms, the seat plate is formed with a pair of integral lugs 21, projecting diametrically therefrom,- and also with a central boss 22 adapted to seat in the recess 14 locking latch, or bent end 17 of the latch to lock the two plates relative to each other. In assembling the parts, with the two plates attached to their respective members, the plates are operatively connected by slipping one of the lugs 21 under the flange 13 while the other lug is passed through the opening 2a of the flange, it being understood that the opening is of sufficient size to permit passage of the lug. WVhen the seat is placed in position the seat plate pushes down upon the latch 17, the boss22 seats in the recess I-f, and the lugs 211nay move freely under the flange 1.3 being guided thereby.

The seat may now be swung upon its central support until the latch encounters one of the depressions or openings 23, when the weighted end of the latch will cause the latch end to pass through the opening and lock the two plates. Or, if a further adjustment is desired, the weighted end of the lever may be held up by the hand or foot so that the latch end will not encounter the passing openings 23, until the desired position of the seat is attained, then by releasing the weighted lever the latch will engage the opening 23 and lock the parts.

The diflerent positions of the seats are indicated in Figs. 7 to 11 wherein the seats of Fig. 7 are facing in the same direction, the usual arrangements; in Fig. 8 the seats are facing in opposite directions, tte a tte;

in Fig. 9 the seats are arranged to provide seat allows the seat a free and easy motion forward or backward, or to either side. The portable shelf 25 may be attached by its legs 26 to the side bars and forms acon- YQIIlBIiCB for sewing etc.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

The combination with a supporting frame and a base plate having an overturned ring forming an annular flange with an opening therein, of a revoluble seat plate with a central boss supported on the base plate and a pair of diametrically arranged. lugs extending under said flange, and means for locking said seat plate in any one of a pinrality of positions.

In testimony whereof he affixes his signature in presence of two witnesses.
